Improved Documentation Inclusivity

[ps-19]

Summary

Primary Aim Of the Patch is:

Added more visibility in docs.
Removed Errors and grammatical mistakes.
Removed extra spaces and tabs created to make sample code and command error-less and concise.
Dear sir/mam,
I am new to LLVM and contribution here is complicated and different. I am working on a issue, so trying to understand, how to submit a patch using this contribution. Kindly merge the request. I am really good at coding i am coding since 14 yrs age, development and open source

A patch which addresses same issue has already been submitted https://reviews.llvm.org/D122719 .

@xbolva00 can you please review https://reviews.llvm.org/D122719 patch. Is their any thing wrong in it?

 # The LLVM Compiler Infrastructure
 
 This directory and its sub-directories contain source code for LLVM,
 a toolkit for the construction of highly optimized compilers,
 optimizers, and run-time environments.
 
 The README briefly describes how to get started with building LLVM.
 For more information on how to contribute to the LLVM project, please
 take a look at the
 [Contributing to LLVM](https://llvm.org/docs/Contributing.html) guide.

 ### Overview
 
 Welcome to the LLVM project!
 
 The LLVM project has multiple components. The core of the project is
 itself called "LLVM". This contains all of the tools, libraries, and header
 files needed to process intermediate representations and convert them into
-object files.  Tools include an assembler, disassembler, bitcode analyzer, and
-bitcode optimizer.  It also contains basic regression tests.

+C-like languages use the [Clang](http://clang.llvm.org/) frontend. This
 component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode
 -- and from there into object files, using LLVM.
 
 Other components include:
 the [libc++ C++ standard library](https://libcxx.llvm.org),
 the [LLD linker](https://lld.llvm.org), and more.

 This is an example work-flow and configuration to get and build the LLVM source:
 
 1. Checkout LLVM (including related sub-projects like Clang):
 
      * ``git clone https://github.com/llvm/llvm-project.git``
* ``cmake -S llvm -B build -G <generator> [options]``
         * The default target (i.e. ``ninja`` or ``make``) will build all of LLVM.
 
         * The ``check-all`` target (i.e. ``ninja check-all``) will run the
           regression tests to ensure everything is in working order.
 
         * CMake will generate targets for each tool and library, and most
           LLVM sub-projects generate their own ``check-<project>`` target.

+        * Running a serial build will be **slow**. To improve speed, try running a
           parallel build.  That's done by default in Ninja; for ``make``, use the option
           ``-j NNN``, where ``NNN`` is the number of parallel jobs to run.
           In most cases, you get the best performance if you specify the number of CPU threads you have.
           On some Unix systems, you can specify this with ``-j$(nproc)``.
