This PR makes the following improvements to the ARM_CRx_No_GIC port-
1. Remove inline assembly and move all the assembly code to the portASM.S
file.
2. Add support for configUSE_TASK_FPU_SUPPORT -
- When configUSE_TASK_FPU_SUPPORT is defined to 1, tasks are created
without floating point context. Tasks that want to use floating point, need
to call portTASK_USES_FLOATING_POINT(). This is the current behavior.
- When configUSE_TASK_FPU_SUPPORT is defined to 2, each task is created
with a floating point context.
If left undefined, configUSE_TASK_FPU_SUPPORT defaults to 1 for backward compatibility.
3. The application writer can now implement vApplicationSVCHandler to handle the
SVC calls raised within the application. SVC 0 is used for the yield kernel operation
and the application can use all the SVC calls other than 0.

Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the five sample memory allocators as described on the https://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler, where the directory name denotes the compiler specific files the directory contains. For example, if you are interested in the [compiler] port for the [architecture] microcontroller, then the port specific files are contained in FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the only port you are interested in then all the other directories can be ignored.
